Find every accessible text pairing hiding inside the palette.

What does the accessible color palette contrast checker do?

Paste named HEX colors to calculate a complete contrast matrix, identify normal- and large-text combinations, and expose palette pairs that need another role or shade. The immediate result is a WCAG contrast matrix for every supplied color pair. That makes the tool useful when a focused question needs an answer before a file is handed off, a campaign is trafficked, or a production workflow begins.

The scope is intentionally narrow. It is designed for translating one responsive or layout decision into implementation terms, not for replacing the complete production process. A useful result should make the next decision clearer while leaving the original file, design, or workflow under the user’s control.

Palette values are calculated locally and are not uploaded. Local processing reduces unnecessary data exposure, but it does not remove the need to follow the privacy, confidentiality, and retention requirements that apply to the source material.

How should the accessible color palette contrast checker be used?

Start with the same input that will be used in production whenever possible. Draft content, substitute files, and approximate dimensions can be useful during exploration, but the final check should use the actual export, final copy, destination, or supported range.

Work through the steps in order and keep the generated result beside the source. If the result identifies a warning, decide whether it is a real production problem, an acceptable tradeoff, or a limitation of a browser-based inspection before changing the underlying work.

• Paste up to twenty named HEX colors from the design system.
• Review every foreground and background pairing against normal- and large-text thresholds.
• Assign semantic roles, test real component states, and validate non-text contrast separately.

How should the result be interpreted?

A browser tool can make measurable signals visible, but it cannot reproduce every application, platform, rendering engine, policy, or team constraint. Treat the report as evidence for a decision rather than a universal guarantee. The strongest verification is the rendered browser result across real content, supported viewports, and target browsers.

Pay particular attention to edge cases that are easy to miss during a quick check: unusual fonts, long or localized content, hidden metadata, external dependencies, different aspect ratios, browser-specific behavior, and last-minute source changes. Re-run the tool whenever the production input changes materially.

• A passing ratio does not guarantee that hierarchy, font weight, or readability is good.
• Check hover, disabled, focus, selected, error, and dark-mode states.
• Logos, charts, controls, boundaries, and images can follow different requirements from ordinary text.

Common questions about accessible color palette contrast checker

What contrast ratios does the matrix use? It reports the commonly used WCAG thresholds: 4.5:1 for AA normal text, 3:1 for AA large text, 7:1 for AAA normal text, and 4.5:1 for AAA large text.

Can the tool check gradients or background images? No. It calculates solid color pairs. Gradients, transparency, imagery, overlays, and browser rendering require testing the actual component at its least-contrasting point.

Is the accessible color palette contrast checker free? Yes. You can use it without an account or signup. The focused result is generated directly in your browser.

When does Weblify become the better workflow?

The free tool is the right choice for a quick individual check, calculation, preview, or template. It remains useful even if the task only occurs once and no broader production workflow is needed.

Weblify becomes more practical when the same job turns into inspecting real Figma layers and producing implementation-ready HTML, Tailwind, React, or Vue output. At that point, keeping the work close to the Figma source reduces repeated exports, copy-and-paste steps, inconsistent decisions, and handoff drift.

Before adopting any workflow, compare the time spent on the recurring manual process with the setup and review required by the tool. The goal is not to add another application; it is to remove repetitive work while preserving the quality checks that still need human judgment.
